GOAL AND OTHER SOLID GARBONACEOUS SUBSTANCES Application filed June 4, 1927, Serial No. 196,599, and in Great Britain June 7, 1926.

This invention relates to retorts for the distillation of coal and other solid carbonaceous substances, and is especially applicable to vertical retorts.

The invention has for its object to provide simple and effective means for the discharge and reception of the residue of distillation and for its convenient removal under conditions in which the retort and the residue are inaccessible to air in the operation.

According to the invention I provide means for discharging retorts comprising in combination a skip or tub adapted for the reception of coke or residue on the downward discharge from retorts, provided at the upper end only with an annular cavity or channel to contain a sealing liquid or substance and means, such as an extension from the retort or retorts or from an intermediate discharging chamber or the equivalent, provided beneath the retorts, adapted to make with the annular cavity of channel aforesaid a gas tight seal on a short relative movement of one or other of the parts by which the gas tight seal is made.

The invention comprises the modifications hereinafter described.

The invention is hereinafter described by way of example with reference to the accompanying diagrammatic drawing in which Figures 1 and 2 are end and side elevations of a construction employed according to the invention, both views being partly in section, Figure 2 being in part cross-section on the line 22 of Figure 1.

As illustrated in the accompanying drawing the skip or tub a is advantageously mounted upon wheels I), and a table 0 may be provided in position beneath the retorts (Z upon which the skip or tub a may be raised to the extent necessary to complete the seal.

The skip or tub a may be provided of a circular, oblong or other transverse sectional shape corresponding to the lower end of the retort or corresponding to an intermediate discharging chamber 6. In the construction illustrated each of a pair of retorts is mounted upon a base part 7, both of which base parts are in turn supported upon a common frame part or extension g, which is carried upon joists or angle irons h the ends of which are respectively supported in the setting. The frame part or extension 9 serves as the intermediate discharging chamber 6, and the 101sts or angle irons hserve to carry a downwardly extending rim g which is provided with a downwardly and inwardly inclined surface 9 At its upper end the skip or tub a is provided with a continuous annular cavity or channel a for containing water or othersealing liquid or fine sand or similar finely divided material, so that thus on the table 0 carrying the skip or tub a being raised into the position indicated in dotted lines in Figure 1, the lower edge of the rim g will enter the sealing liquid or material in the annular cavity or channel a to complete the seal, and the part 9 will prevent any part of the coke or residue passing into the annular cavity or channel.

The annular cavity or channel a may be formed by means of a continuous outer wall or ring secured to the wall of the skip or tub a near its upper end, which outer wall or ring may be of a substantially L shaped transverse section, one part of the section forming the outer wall of the annular cavity or channel and having its inner edge downwardly diverted to form a downwardly extending vertical flange by which the outer wall or ring may be secured to the wall of the skip or tub, by riveting or otherwise.

Any known simple means may be provided 7 for raising the table or platform 0. Such means may consist of a hydraulic cyllnder and plunger i, or a screw-threaded spindle or gear, or toggle lever mechanism or the equivalent, and the means for raising the skip or tub may be more or less permanently provided beneath the retort or retorts cl, or as is preferably the means employed for the purpose may be mounted upon movable carriage which may be so provided with rails that the skip or tub a may be run on to the table carried by it, from a prepared position in which rails may be disposed in alignment with those upon the table.

At a position immediately beneath the bottom door or closure of the retorts, a gas and vapour outlet pipe Z may be provided leading to the hydraulic main, the pipe being connected to a pipe in the main, the lower end of which dips slightly below the surface of the liquid therein.

. I claim:

1. Means for discharging retorts comprising an intermediate easing into which the retort residue passes on discharge therefrom, a downward annular extension from the said intermediate casing, a skip adapted to run on rails to bring the said skip beneath the said extension, an annular channel provided at the upper part of the said. skip and adapted for the reception of a sealing substance and for the admission within it of the said annular extension, and means for raising and lowering said skip to cause the said extension to pass into and out of the said annular channel, substantially as described.

2. Means for discharging retorts comprising an intermediate easing into which the retort residue passes on discharge therefrom, a downward annular extension from the said intermediate casing and an inwardly inclined wall also extending from the said intermediate casing, a skip adapted to run on rails to bring the said skip beneath the said extension, an annular channel provided at the upper part of the said skip and adapted for the reception of a sealing substance and for the admission within it of the said annular extension, and means for raising and lowering said skip to cause the said extension to pass into and out of the said annular channel, substantially as described.

CHARLES HENRY PARKER.
